The execution of the gold nmm looks pretty solid. Recomendations would be to add one or two more lights for your photography so as not to use the flash. The shadows cast by the flash throw the pic details off.
Lovely painting. Would rate this 7.5 if i could, but i can´t, sorry. Just a little tip, you have a nasty mouldline in the front of the horse´s hair(sorry for bad eng.) Keep it up, its nice maaaaan ;)
